Your car is made up of complicated systems. And, even without saying, it’s a fact that auto mechanics are not know-it-all in the automotive field. There are also some things they’re not aware of, some problems that they cannot solve as easily as they solve other problems. That said, you have to decide with whom to entrust your car when you need any auto part or system repaired.
Generally, there are two categories of mechanics and repair shops: the specialists and the generalists.
The specialists are those shops and mechanics that focus on and specialize in the repair of a particular part or system. For example, a mechanic may specialize in transmission repair and rebuilding. You can expect him to know all about both manual and automatic transmissions, down to the very last component or problem. You can also expect that mechanic to know all about the developments in the field of transmission systems.
On the other hand, the generalists are those shops and mechanics who can work on all systems and parts of vehicles in general, the so called jack of all trades in the auto repair industry, without necessarily specializing in any of the said parts and assemblies.
If you need a repair done in your vehicle, you can choose between a generalist and a specialist shop or mechanic. A specialist is a good pick for very serious problems that generalists may not be able to handle. However, should you have a problem whose effects are evident not only on a single system but on a wide range of systems, you might want to go for a generalist, one that can handle the problems plaguing different parts and systems. The selection could be crucial as this can spell the difference between the success and failure of the repair.
